Timmy Burch is a male fourth grader at South Park Elementary. He first appeared in the Season Four episode, "The Tooth Fairy Tats 2000", and is voiced by Trey Parker. He is handicapped, uses a wheelchair to get around, and has a limited vocabulary consisting only of his own name and a small handful of other words and phrases. After a decade of being known simply as "Timmy", his full name was revealed to be "Timmy Burch" in the episode "T.M.I." when his name was posted on the poster containing the kids' growth differentials.
